Hi All, love this forum, tremendous source of information! Been reading for a couple of years and now need collective wisdom on damaged equipment replacement options.
Original pool configuration: In ground pool, 32,000 gallons with attached spa and waterfall, 400,000 BTU Hayward heater, Hayward 2HP, 2 speed filter pump, single speed waterfall pump, air blower, lights. Everything is controlled by older Hayward Aqua Logic PL-PS4 control panel. Pool and all equipment are about 8 years old.
A couple of weeks ago the heater (which hasn't been used since last winter) caught fire, which melted heater side panel, overheated and blew up filter motor run capacitor and went up on adjacent fence.
Luckily, my neighbors noticed it early enough and called 911. After opening the heater I discovered that rats build a nest inside the heater and chewed on wires causing the fire. 
The damage is: heater, control board (seems to be fried by electric short) and possibly the pump motor. Since I need to replace all those, I thought I might as well get some upgrades (VS pump, newer control panel). I am technically savvy and have no problems working with electric and plumbing components, so I am going to do all repairs myself. I've been doing some online research in the past few days and I think I narrowed it down to a couple of combinations:
option A: Hayward EcoStar SP3400 pump, OmniLogic control panel, Hayward H400FDN heater.
option B: Pentair IntelliFLow pump, IntelliTouch controls, MasterTemp 400,000 BTU heater.
My questions:
1) Are there any caveats with configurations listed above? Any known problems with components reliability, compatibility and configuring issues I should be aware of?
2) It is probably a good idea to stay with the same vendor for all components, but if I decide to use different brand components, say Pentair control board and Hayward heater, am I looking for any trouble or are they generally compatible?
3) Hayward seems to be the only company that gives 1 year warranty on owner installed equipment, but being a home automation geek I really like Pentair automation controls better (based on their description and home automation integration options). I would like however, to hear first hand user experiences with Hayward OmniLogic vs. Pentair IntelliTouch. Trying to decide for myself whether it is worth losing warranty coverage on Pentair equipment due to self installation
Thank you all for reading the story and for your comments!
